Oracle released its latest version of its database last week .
Installed it this week and started playing with that.
DBCA
====
While creating database via dbca , it has two buttons "Alert Log" and "Activity Log" . By clicking on "Alert Log" , a Java popup window displays the contents of the (legacy ) alert log.
SQL Feature
===========
Started with the "tiny" new feature in SQL . I believe , it will be useful in pagination queries.
SQL> select empno , ename , hiredate from emp order by hiredate;
EMPNO ENAME HIREDATE
---------- ---------- ---------
7369 SMITH 17-DEC-80
7499 ALLEN 20-FEB-81
7521 WARD 22-FEB-81
7566 JONES 02-APR-81
7698 BLAKE 01-MAY-81
7782 CLARK 09-JUN-81
7844 TURNER 08-SEP-81
7654 MARTIN 28-SEP-81
7839 KING 17-NOV-81
7900 JAMES 03-DEC-81
7902 FORD 03-DEC-81
7934 MILLER 23-JAN-82
7788 SCOTT 19-APR-87
7876 ADAMS 23-MAY-87
14 rows selected.
SQL> select empno , ename , hiredate from emp order by hiredate fetch first 50 percent rows only;
EMPNO ENAME HIREDATE
---------- ---------- ---------
7369 SMITH 17-DEC-80
7499 ALLEN 20-FEB-81
7521 WARD 22-FEB-81
7566 JONES 02-APR-81
7698 BLAKE 01-MAY-81
7782 CLARK 09-JUN-81
7844 TURNER 08-SEP-81
7 rows selected.
As it can be seen from the example , I can display only the part of the resultset based on %.
Will continue to explore and post my findings as I come across.
Comments Welcome.
